| Abstract: | Perzna model was employed to simulate the SHPB dynamic compression test of a low alloy steel representing strain-rate sensitivity,and the stress-strain curve was obtained and compared with experimental data.The results indicate that the stress-strain curve of simulation matches experimental curve very well,and the deviation is less than 8% when strain value is more than 2%. |
